中文摘要：

为了提高复合材料齿轮的承载能力,需对其进行设计和分析.通过Pro/E软件实现对直齿圆柱轮的参数化建模,并将三维模型导入到有限元软件ANSYS中,然后采用模压成型工艺,制备短切玻璃纤维增强的酚醛环氧复合材料板,以其力学性能作为设计参数,通过有限元软件对复合材料齿轮在一定载荷条件下的应力分布状态进行了分析.研究结果表明,键槽与啮合轮齿的相对位置会影响复合材料齿轮的应力分布状况,齿顶和齿根最大压缩应力与输入载荷呈线性关系,而齿根最大拉伸应力与输入载荷关系曲线中出现一段平台区.通过对BMC复合材料齿轮的静力学分析,为复合材料齿轮的改进设计提供一种实用的方法.

英文摘要：

In order to improve the bearing capacity of composite gears, the design is necessary. Using the interface technology between Pro/E and ANSYS software, a 3D parametric model of involute cylindrical spur gear designed in Pro/E is inputted into ANSYS. Short glass fiber reinforced phenolic resin /epoxy resin bulk moulding compound （BMC） composites were prepared by hot press moulding processing and their mechanical properties were measured as the simulation parameters. The simulations analysis of stress status of composite gear made of phenolic resin/epoxy resin BMC under a certain load is made in this paper. The gear was greatly affected by the relative position between results show that the stress distributions of the composite the keyway and loaded teeth. The maximum compression stress of the teeth tip as well as the teeth root was nearly linear with the input load. In addition, a platform appeared in the diagram on the relations between the maximum tensile stress of the teeth root and the input load. Through the researches in this essay, a practical approach for composite gears design were provided.
